This looks good. @KristofferC Can we merge? |
|
We should probably merge JuliaPackaging/Yggdrasil#3655 first, right? cc: @staticfloat |
|
It doesn't matter. This is just fixing the Julia source build. Once the Yggdrasil PR is merged, we can bump deps/Versions.make and I am sure 2 other places that I always forget at which point the fix will start appearing in the binaries. |
|
Once JuliaRegistries/General#45875 lands we should update versions and refresh checksums |
|
After updating the version number manually, I updated the checksum with Is there anything else I need to do? |

There was a problem hiding this comment.
The above two lines of checksums are not updated, is this the expected behavior of the contrib/refresh_checksums.mk script?

Issue Description
OpenBLAS, or more precisely CBLAS, will crash when you multiply two large matrices together.
After testing, this issue was found to occur in OpenBLAS v0.3.10, and was fixed in v0.3.12 and later.
Conditions for problem reproduction
Test code
LinearAlgebra.BLASNote: You can replace
Julia-1.6.x/bin/libopenblas64_.dllto test other dlls.ccallYou can get the compiled product with the patch applied from the AzurePipeline in JuliaPackaging/Yggdrasil#3655.
e.g.: OpenBLAS.v0.3.10.x86_64-w64-mingw32-libgfortran5
Patch code
With some
git bisect(#40963 (comment)), I found that commit b205323 seems to fix this issue.But, I'm not sure if this fully fixes the issue, more testing may be needed.
fix #40963.
Note: Buildbot uses the compiled product of BinaryBuilder.jl, so the bug is not fixed in the CI output artifacts.You can download the compiled product of BinaryBuilder.jl with patch applied in JuliaPackaging/Yggdrasil#3655, replace the
libopenblas64_.dllthat comes with julia, and test it.We may need to merge JuliaPackaging/Yggdrasil#3655 to get the repairedOpenBLAS_jll.jlfirst, and then update the OpenBLAS version in julia's dependency.
